Archives of Foundry Engineering continues the publishing activity started by Foundry Commission of the Polish Academy of Sciences (PAN) in Katowice in 1978. The initiator of it was the first Chairman Professor Dr Eng. Wacław Sakwa – Corresponding Member of PAN, Honorary Doctor of Czestochowa University of Technology and Silesian University of Technology. This periodical first name was „Solidification of Metals and Alloys” , and made possible to publish the results of works achieved in the field of the Basic Problems Research Cooperation. The subject of publications was related to the title of the periodical and concerned widely understand problems of metals and alloys crystallization in a casting mold. In 1978-2000 the 44 issues have been published. Since 2001 the Foundry Commission has had patronage of the annually published “Archives of Foundry” and since 2007 quarterly published “Archives of Foundry Engineering”. Thematic scope includes scientific issues of foundry industry:
- Theoretical Aspects of Casting Processes,
- Innovative Foundry Technologies and Materials,
- Foundry Processes Computer Aiding,
- Mechanization, Automation and Robotics in Foundry,
- Transport Systems in Foundry,
- Castings Quality Management,
- Environmental Protection.
In the paper presented are results of a research on influence of electrical and physico-chemical properties of materials being parts of
multicomponent and multimaterial systems used in foundry practice on efficiency and effectiveness of microwave heating. Effectiveness
of the process was evaluated on the grounds of analysis of interaction between selected parameters of permittivity and loss factor, as well
as collective index of energy absorbed, reflected and transmitted by these materials. In the examinations used was a stand of waveguide
resonance cavity for determining electrical properties and a stand of microwave slot line for determining balance of microwave power
emitted into selected materials. The examinations have brought closer the possibility of forecasting the behaviour of multimaterial systems
like e.g. model, moulding sand or moulding box in microwave field on the grounds of various electrical and physico-chemical properties.
On the grounds of analysis of the results, possible was selecting a group of materials designed for building foundry instrumentation to be
effectively used in electromagnetic field.
